Definitions
- the present invention relates to an apparatus supply of a cryogenic liquid, of the type including a thermally insulated main line in which is mounted a throttling member of the liquid flow.
- the start of nitrogen vaporization before closing the box, expels air from the box, ensuring thus inerting the product. Then, after closing the box, the end of the nitrogen vaporization puts the overpressure box, which allows it to be handled at will without risk of denting or crushing.
- the invention aims to allow adjustment improved flow of cryogenic liquid. To this end, it relates to a device of the aforementioned type, characterized in that it includes a degassing pipe tapped on the main pipe downstream of the organ strangulation.
- the invention also relates to a valve cryogenic for such an apparatus.
- This valve cryogenic of the type comprising a valve body which defines an upstream pipe section, a section of downstream pipe, as well as a seat located between these two sections, and a shutter mounted movable in the body by relative to the seat, is characterized in that the body of valve has a hole that opens into the part upper section of the downstream section.
- the seat is frustoconical and converge downwards and is extended downwards by a cavity
- the shutter includes a frustoconical conjugate part of the seat and a lower part adapted to be received with play in said cavity when the shutter is in position closing.
- the invention also relates to an installation for packaging a product in containers scroll, comprising a nitrogen supply apparatus liquid as defined above, arranged above the container conveyor, between a filling station containers with the product and a closing station containers.
- FIG. 1 Schematically shown in Figure 1 a liquid product packaging installation non-carbonated in a row of cans cylindrical contiguous 1. These boxes are carried by a conveyor 2 and pass successively, in the direction of arrow F, under a station 3 for filling boxes with the product, under a device 4 for supplying a net 5 of liquid nitrogen, and under a crimping station 6 a waterproof cover 7.
- Posts 3 and 6 are conventional, so that only the apparatus will be described below 4.
- the apparatus 4 comprises, from upstream to downstream, a double-shell liquid nitrogen tank 8, the upper openings of the two envelopes being connected by a thermally insulating collar 9.
- the envelope exterior 10 is equipped with a fixing structure 11 to an appropriate support (not shown).
- Col 9 is crossed by a supply line 12 controlled by a 12A liquid nitrogen level sensor in the enclosure inside 13 of the tank, and by a degassing 14 leading to the surrounding atmosphere.
- the tank is additionally equipped with various accessories conventional, not shown.
- the bottom of the envelope 10 has an orifice from which the outer casing 15 of a pipe starts main 16 for supplying liquid nitrogen.
- This pipe consists of a first section 17 extending vertically downward, from a second horizontal section 18, and a third section 19 extending vertically downwards.
- a liquid nitrogen distribution head 22, interchangeable is provided at the downstream end of the driving 16.
- valve 23 In the horizontal section 18 is mounted a valve 23.
- the latter ( Figures 1 and 2) includes essentially a valve body 24 surrounded by a thermal insulation 25, a shutter 26 actuated by a vertical control rod 27, and an actuator 28 located at the upper end of the rod 27.
- the body of valve 24 has, from its upper face, a vertical bore 29 extended downwards by a counter bore blind with the same axis X-X, which defines a cavity cylindrical 30.
- a section of upstream pipe 31 inclined downwards, from a side face of the valve body and opens into the cavity 30. Its diameter is slightly lower than that of the counterbore ( Figure 3).
- a downstream pipe section 32 inclined downwards in the same way as section 31, starts from the bore 29 and opens onto the opposite side face of the body valve.
- a hole 33 made in the downstream part of the body 24 opens at a point intermediate of the downstream section 32 and is connected to joint sealed, by welding, to a degassing tube 34.
- This last ( Figure 1) extends upstream between the tube 20 and the casing 15 of the pipe 16, then in space inter-wall of the tank 8, and ends with a butt 35 which crosses with watertight seal the part inner envelope 13 and opens into this one.
- the bore 29 and the counter bore 30 are connected by a frustoconical seat 36.
- the shutter 26 has a intermediate part 37 frustoconical conjugate of the seat 36, fitted with a Teflon seal 38, a lower part 39, also of general shape frustoconical but with a much larger opening angle weak, and an upper link 40. This last is connected to the lower end of the rod 27 by a ring 41 which allows a slight clearance angle of the shutter around the X-X axis.
- part 37 of the shutter 26 is applied to the seat 36, and its lower part 39 is received with a large clearance in the cavity 30 (low position in Figure 3).
- the shutter In operation, the shutter is lifted from its seat (high position in dashed lines in Figure 3), which connects the pipe sections 31 and 32.
